lvugg HAIR CURLING IMPLEMENT BACKGROUND OF THE INVENTION This invention relates to hair curling implements, such as curling irons for example, and is concerned-particularly with hair curling implements of'the type which are used to set or curl hair by the application of steam.

It is an object of the present invention to provide an implement for the settingof curls of different sizes, the implement providing an. expansiblev mandrel onto which the hair is wound and clamped, and means for applying steam to the interior of the mandrel, which is perforated to allow passage of the steam to the hair.

A hair curling implement in accordance with the invention comprises an elongated curling arm, the curling arm having an elongated tubular barrel with a longitudinally extending slot therein; steam generating means mounted within said barrel; a clamping arm pivotally mounted on the curling arm and adapted in the clamped position to cooperate with a longitudinally extending upper region of the barrel; an expansible mandrel constituted by a resilient perforate screen anchored along one longitudinal edge to the barrel and extending through said slot, the perforate screen being looped into a generally cylindrical configuration encircling a longitudinally extending lower region of the barrel, said lower region of the barrel having perforations for the passage of steam from the steam generating means to the interior of the mandrel; a rotary anchoring member mounted within thebarrel for rotation about a longitudinal axis, the anchoring member providing a longitudinally extending arm offset from said axis, the screen being anchored along a second longitudinal edge to said arm of the anchoring member; and manually rotatable means mounted on said curling arm and coupled to the anchoring member for rotating the anchoring member whereby to expand or contract the mandrel. v i

Referring to, the drawings, the hair curling implement comprises a hollow curling arm having an elongated tubular barrel 10 of circular cross section and a hollow handle portion 11 of plastic. The'barrelis formed with a longitudinally extending slot 12, the purpose of which will become apparent subsequently. A conventional clamping arm 13 is pivotally mounted on the curling arm, being connected thereto by a pivot pin 14 (FIG.

2), and being spring-biassed to the clamped position by a torsion spring 15. The clamping arm 13 is provided at one end by a plastic handle portion 16, which can be operated by the thumb of a user holding the handle portion 11, for manipulating the clamping arm. As illustrated in FIGS. 3 and 4, the clamping arm 13 is shaped to conform to the cylindrical shape-of the barrel l0, and is adapted in the clamped position to cooperate with a longitudinally extending upper region of the barrel.

Extending axially within the tubular barrel 10 is a steam generating assembly comprising an elongated electric resistance heating element 17, this being encased within a metal sheath 18 having a number of grooves or channels 19 extending along the exterior of its lower portion. The encased heating element assembly l7, 18 is in turn encased within a tubular housing 20, the latter being formed with three longitudinal rows of perforations 21 communicating with the grooves 19 so as to permit the passage of steam therefrom to an intermediate annular space or chamber 22 between the housing 20 and the interior surface of the barrel 10. One end of the heated casing 18 is shaped to provide a baffle member 23 of substantially the same outside diameter as the internal diameter of the barrel 10. This baffle member is shaped to provide a labyrinth of channels constituted by a series of interconnected circumferential grooves 24, the labyrinth providing a fluid exit 25 communicating with the longitudinal grooves 19 and a fluid inlet 26 communicating with a flexible supply tube 27.

The curling arm 10 carries an expansible mandrel 28, which is constituted by a resilient, foraminous screen of stainless steel. The screen is rectangular in shape, having an imperforate peripheral region which bounds the foraminous, steam-pervious central region of the screen, and is of a width corresponding to the length of the slot 12 through which the screen extends. The shorter pair of edges of the rectangular screen extend longitudinally with respect to the tubular barrel 10, one of these edges being anchored to the exterior of the barrel by rivets 29, and the other being anchored to a longitudinally extending arm 30 of a rotary anchoring member 31. The rotary anchoring member 31 is mounted at one end of the barrel 10 for rotation about a longitudinal axis, the arm 30 being offset from the axis. As illustrated in the-sectional view of FIGS. 7 and 8, one end of the barrel 10 provides a stop 32 which is engageable with an abutment 33 on the rotary anchoring member to limit rotation of the latter in either direction. The rotary anchoring member 31 is coupled to a manually rotatable member 34 of plastic. The member 34 is mounted at one end of the barrel l0 and connected thereto by a swivel joint so as to be coaxial with the barrel. The foraminous screen is looped into a generally cylindrical configuration, extending from one of.

its anchored edges to the other, so as to form the mandrel 28. The screen thus encircles a longitudinally extending lower region of the tubular barrel 10, which lower region is formed with rows of perforations 35 to permit the discharge of steam from the chamber 22 to the interior of the mandrel. In order to expand or contractthe mandrel 28, the user simply rotates the member 34 in the appropriate direction.

Treatment liquid or water is supplied from a replaceable cartridge 36, forming a reservoir, mounted in the handle portion 11. The cartridge 36 communicates with a deformable container 37 by way of a soft rubber cap 38, and is provided with a one-way valve 39 for controlling the supply of liquid from the cartridge. The deformable container 37 communicates by way of a one-way valve 40 with the tube 27. The handle portion 11 is shaped to provide internal abutments 41 which engage the container. The handle portion 11 also carries a manually engageable push button 42, having an abutment 43 which is adapted to engage the container for deforming the container. Thus, when a user depresses the button 42, a metered discrete quantity of liquid is squeezed out of the container via the valve 40. This liquid passes via the tube 27 into the labyrinth of channels 24 and thence to the grooves 19. The liquid is vaporized, steam issuing from the perforations 21 into the space 22, and from the space 22 to the interior of the mandrel via the openings 35.
